可能的重复:
我有两个应用程序说应用程序“A”和应用程序“B”。应用 A 有一项具有自定义权限的服务,而应用 B 想要调用该服务。以下是我的代码片段
应用 A: : 清单文件
<service
android:name="SendService"
android:permission="android.permission.MyService">
<intent-filter>
<action android:name="com.example.calledactivity.MyServiceCaller" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="sms" />
<data android:scheme="smsto" />
</intent-filter>
</service>
在这里,我使用权限android.permission.MyService保护了我的服务
在App B Manifest 文件中具有以下权限
<uses-permission android:name="android.permission.MyService"
android:description="@string/app_name"
android:label="@string/menu_settings" />
最后调用应用程序 A 的服务,我在应用程序 B 中使用以下代码
Intent i = new Intent("com.example.calledactivity.MyServiceCaller", Uri.parse("sms:2223333"));
getApplicationContext().startService(i);
当我运行这个示例时,我得到了带有以下堆栈跟踪的 SecurityException

我已经经历了上面提到的许多线程,但没有一个能够解决我的问题。所以,我再次提出了这个问题。
谢谢
